TRACTION-WHEEL CONNECTION FOR POWER-DRIVEN VEHICLES.

Specification of Letters Patent.

Patented Apr. 29, 1919.

Application filed April 23, 1918. Serial no. 230,256.

To all whom it may concern:

Be it known that I, COLONEL W. LANHAM, a citizen of the United States, residing at hicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Traction-Wheel Connections for Power-Driven Vehicles, of which the following is a specification.

My invention relates to power driven ve- 'cles employing traction wheels, one of which is rotatably mounted on a shaft and in connection with which, means are provided for alternately clutching and unclutching the my invention having been devised for use, more particularly, in corn planters of the so-called wireless check-rower type.

My primary object is to provide for the mounting of the one of the supporting Wheels of the vehicle, which is rotatably mounted on the supporting shaft, in such a manner that it may be clutched to and unclutched from the shaft under the control of the operator, and in the transporting of the vehicle, the tached therefrom without disturbing the bearings and readily applied thereto in assembling the parts of the machine.

Referring to the accompanying drawings,

Figure 1 is a plan view of a corn-planter in connection with which I have illustrate my invention. Fig. 2 larged section taken at the line Fig. 1 and viewed in the direction of the arrows. Fig. 3 is aperspective view of the is an eninnerend of thehub-portion of the wheel and the outer endof a clutch sleeve cooperating therewith; and

Fig. 4, a view in elelation. v p

It may be stated asa premise to the description of my particular improvement that the corn-planter, as, shown, comprises a main frame '6 carrying bearings 7 and 8,

through the medium of which the main shaft 9 is supported relatively to the frame. A second shaft, represented at 10, extends crosswise of the frame 6 and parallel with the shaft 9 and carries a marking wheel ll;

9, operates corn which, through the shaft feeding devices (not shown), at the ends of this shaft cooperating with the seed-hoppers 12 mounted on the frame of the machine, the shaft 10 and parts carried therey being so mounted that they may be bodily Wheel to or from the shaft,

operating clutch wheel may be readily de-- parts inassembled reraised to lift the wheel 11 out of engagement with the ground when desired.

The shaft 9 is provided atone end with a supporting wheel l3v rigidly connected therewith and at its opposite end with a supporting Wheel let .journaled thereon.

' a clutch member 15 roshaft 9 to be movable into and out of clutch engagement with the clutch 15. The shaft toward its opposite end, carries two oosections '20 and 21, the being provided with a reduced diameter, which encircles the shaft 9 and is interposed between the latter and the bearing 7, the outer end of this sleeve presenting two diametrically opposed lugs 23, which extend into recesses 24 in the hub 25 of the wheel 14, this hub extending wholly beyond theouter end of the bearing/7, the parts just described being secured together in theinterlockin relation stated for connecting together the wheel 25 and clutch clutch section 21 sleeve member 22 of shaft 9 and is held against accidental displacement by a pin 27 extending through the cap and shaft. The reduced portion forms a shoulder 22 which opposes the inner end of the bearing 7 and forms means limiting the movement of the sleeve 22 in an outward direction.

The member 20 is slidable along the shaft into and out of intermeshing relation with the clutch section 21 and this slidable clutch member and also-the clutch member 19 are adapted by means shown, but which need not be described so far as the present invention is concerned, to simultaneously clutch the sprocket wheel 16 and shaft 9 to cause them to the wheel 14 to the operate as a unitary structure and in the particular arrangement shown, to rotate in unison with the markin wheel 11. It may be further stated that in the arrangement shown, the operator may, at Will, unclutch the wheel 14 from the shaft by operating the clutch section 20, thus permitting the vehicle to be readily moved in a circular path, as for example in turn-- ing it around, the Wheels thus having a dif wheelsremoved from the machine.

foregoing de .While I have illustrated and described a particular construction embodying my inventlon, I do, not WlSll to be understood as intending to limit it thereto, as the same may be variously "iodified and altered without departing from the spirit of my l11V611t1OIL I claim as new and desire to secure What byLetters Patent is:
